This invention relates to an apparatus for the production of ozone from oxygen or from gases containing oxygen (air) with or without the use of ultra-violet rays.

According to recent researches ozone is of very high therapeutic importance and a condition is that it be used in a non-irritating form, in moderate not too high concentration and free from nitric oxides and so forth, that is to say in the pure condition but diluted with gases non-injurious to the body such as oxygen.

The main object of the invention is to provide means to apply the ozonized gas in a predetermined amount and with a variable pressure.

The method and manner of application necessitates a very fine adjustment of the gas pressure and the quantity of gas. Under some circumstances a variation of the ozone concentration is also desirable. For conducting it to the point of application, movable, flexible parts should be used such as tubes so constructed that the guiding of the instrument by hand is made easy. India-rubber tubes however are rapidly corroded by ozone and ordinary metal tubes are either too rigid or by reason of jointing with rubber and similar substances do not satisfy the requirements as regards resistibility.

The ozone apparatus according to the present invention, which is particularly adapted for therapeutic purposes, meets these requirements and will be described more particularly with reference to the example shown in the accompanying drawing in which:

Fig. 1 is a view of one form of the apparatus.

Fig. 2 illustrates in a diagrammatical manner the device to measure the quantity of gas, the ozonizer and the tubular connection.

Fig. 3 shows a nozzle and its discharge end (on larger section).

Fig. 4 shows in a side elevation and in a diagrammatical manner the apparatus, one wall being removed.

The apparatus comprises a stand I for a steel cylinder 2 containing pure oxygen. The cylinder 2 is provided with a valve 3 of known construction to which a pressure reducing valve 4 is removably fixed. The reducing valve 4 may be of any known type; it is provided with pressure gauges 5. A tube 6 is attached to said valve 4, said tube leading to an ozonizer 1 arranged within a protective sheet metal casing 8. The latter is rigidly attached to the stand I by a bar 12. The ozonizer 1 is fixed to a wall 9 within the casing 8. The tube 6 leads to a socket ll fixed to and. passing through the wall of the casing. A metallic tube l3 connects said socket l I with a fine adjustment valve l4. The oxygen fl'ows from said valve l4 through pipe 16 to the ozonizer 1 from where the ozonized gas flows through a flexible metal tube 19 to a hand piece 20 with nozzle 2| by which the ozonized gas is to be applied. A pressure gauge I1 isconnected to said valve l4 to show the quantity of gas flowing to the ozonizer I. The automatic interrupter or switch 18 may be of any known make, an index is placed by hand over a scale and after a predetermined time indicated by the position of said index discontinues the delivery of .the electric current and stops the ozonization of the gas. The fine adjustment valve I4 comprises a knob protruding from the front wall of the casing 8 by means of which a plug within said casing may be set. Such valve l4, switch l8 and gauge I! are very well known for like purposes, therefore they are not shown in detail. The arrangement of parts I4, l1, I8 is such that the apparatus may be operated and readings taken from the front side.

The ozonizer 1 may, as shown in the diagrammatical illustration, consist in the known manner of two spaced coaxial glass tubes 2|, 22 fused together at the ends, of which the outer one, 22, is provided with gas inlet 23 and gas outlet 24 and has externally a metal coating 25 connected with an eventually earthed high voltage pole 26, whilst the other tube 2| is provided internally with the conducting coating 21 which is connected to another high voltage pole 28. The conductors are contained in a flexible cable 29 to which a plug is attached.

The poles 26 and 28 are adapted to be connected with a high frequency source (not shown). The time switch I8 in the conductor leading from the pole 26 to the coating 25 automatically cuts oil the current after the lapse of the selected time of treatment. A modification of the ozone concentration may be obtained by suitable adjustment of the voltage; for example, on the primary side of the high frequency source, which may be an alternating current transformer, an inductor (Ruhmkorfi) or a high frequency Tesla, all these parts being of known standard make and working in known manner.

The flexible metal tube l9 consists of a small bore seamless metal tube of metal not to be corroded by ozone; for example, aluminium, which is arranged in numerous turns in the form of a helix and which may be provided with a protecting sleeve 3| of rubber hose, plaited hose or flexible metal tubing. The turns are preferably spaced aparta very small distance when wound,

- as both when the turns bear entirely against one another and when spaced large distances apart the flexibility of the entire tubing is reduced. The minimum diameter of the turns or of the tube depends on the diameter and on the thickness of the .wall of the tube and on the material used.

For injections much smaller gas quantities can be measured by inserting long hollow needles 33, 34 or capillariesof metal, and eventually also suitable filters, at the outlet end or the hand piece 20 of the tube I9, i. e. in or before the applying instrument 2|. From one case tq. another very diverse instruments and exchangeable pieces 2|, canulae, hollow needles. and so forth'are used, which partly permit of a further adjustment of the gas stream. The hollow nee; .dles 33, 34 of rustless (ozone resisting). metal are respectively provided with a collar 35, which when inserted into the conically enlarged bore 35 of he. hand nie e render th j n a ight by screwing down the respective parts. of the hand ie e- {The instruments for the treatment are pref-erably of silver (for instance, the canulae), but also all the articles used as; inserts in the root passa s oi the teeth, the draining tubes, pins and foils are advantageously made of silver to obtain beside the effect of the ozone an increased oligo-. dynamic action. Canulae of silver are especially useful, they are softer and more flexible than the Canulae now in common use and theyproduce in the presence of ozone an increased oligo dynamic action without any destructive action on the ozone; also, silver is known to. have a catalytic action on the decomposition of the ozone.

I declare that what I claim is:'-

1. In an apparatus for producing and applying ozone in therapeutics, the combination of an oxygen tank having a reducing valve at its outlet, a stand for said oxygen tank, a bracket on said stand, a casing supported by said bracket, an ozone generator in said casing, an oxygen supply conduit leading from said reducing valve to said ozone generator, means for fine adjustment of the flow of oxygen into said ozone generator, means for indicating the pressure of the oxygen entering said ozone generator, said fine adjustment means and said pressure indicating means being arranged in said casing, a flexible metallic ozone delivery conduit leading from said ozone generator, a hand piece at the discharge end of said delivery conduit, and an exchangeable applicator consisting of a canula on said hand piece.

2. In an apparatus as claimed in claim 1 in which the delivery conduit consists of a pipe which is helical in form and is composed of flexible metal, the helices of said pipe being; spaced apart.

3. In an apparatus as claimed in claim 1 in which the delivery conduit consists of a pipe which is helical in form and is composed of flexible metal, the helices of said pipe being spaced apart, and a flexible protecting sleeve arranged over said helical metal pipe.

4. In an apparatus asclaimed in claim 1 including a hollow needle of ozone resisting metal fitted into said canaule, said needle being provided with a diametrical enlargement serving as a memher for controlling the passage of ozone through said canula.
